Western Tamiami Trail Flows-Baseline Information and Response to CERP

Project Investigators: Eduardo Patino, Lars Soderqvist

Project Personnel: Andrew Erickson, Noel Wingers, Marty Berry

Project Start Date: 2005 End Date: 2010



The objectives of this study are (1) to develop flow calculation techniques for bridges and culverts under US-41, between Carnestown and County Road 92, and, (2) to provide support to on-going CERP and DOI studies populating hydrologic databases that can also be used by others.

With plans to improve water levels and historic flow-ways in the Southern Golden Gate Estates (Picayune Strand) area north of Tamiami Trail to more natural conditions, changes are expected in the amount, timing, and distribution of freshwater discharge through bridges and culverts under US-41, altering current conditions in the wetlands and estuaries to the south. Hydrologic information throughout the Ten Thousand Islands and adjacent ecosystems is critical to the development of restoration strategies and for the evaluation of restoration results. There is a need to determine current hydrologic conditions in areas south of US-41. There is little hydrologic information throughout the wetlands and estuaries within the study area that could be used in the construction and calibration of the MIKESHE subregional model currently being constructed under the auspices of the CERP Southwest Florida Feasibility Study. There is a critical need for information on freshwater flows across the Trail, ground-water information (including Specific Conductance/salinity) within the marshes south of the Trail, flows at or near the mouth of tributaries, water level, and salinity data throughout the area. The results of this study will provide information that currently does not exist on freshwater flows and salinity trends, effects of weather systems on flow patterns, and on how SGGE and Tamiami Trail Culverts restoration projects affect freshwater inflows and water quality of the estuarine ecosystem within the Ten Thousand Islands area.
